- Rocket Lab Rutherford Engine Explained.
Rutherford is a liquid-propellant rocket engine designed by aerospace company Rocket Lab. Rocket Lab developed the Rutherford engine specifically for the Electron launch vehicle, and it is capable of 4,600 pounds-force of thrust. It uses LOX (liquid oxygen) and RP-1 (refined kerosene) as its propellants and is the first flight-ready engine to use the electric-pump feed cycle.
This video discusses the engineering aspects of the Rutherford engine.

"Let's compare with *traditional* rocket engines..." (shows picture of Raptor)
yep raptor is not traditional but it has no batteries XD
He meant component wise, in with the Raptor uses the same techniques used 60 years ago (Turbopump, a lot of pluming, ect...)
@@pentaborane5034 ye but there’s only 3 full flow combustion engines in history
@@hughm0n6u33 .. and the Raptor is the only one of them that has ever gone beyond the test stand and actually flown.
*laughs in man-powered pump feed
I worked in the space industry for a few years and now back in aviation. Tech like this makes we want to get back into the space stuff. Very exciting time for that industry.
Aviation is having its moments too, with electric and solar-powered crafts in the works.
@@pikachulovesketchup666 yes, battery technology is the bottleneck in a lot of cases. But I would be hesitant to call it a fail, there are many brilliant minds working to solve these problems. We don't know what we haven't yet discovered.
Rocket lab is recruiting in the US 🇺🇸 for their new factory to build their new neutron launch vehicle....

The quality of voice to speech is incredible
Bruh! How did I only now realize how revolutionary rocket lab is?! Also Peter beck remind anyone else of so Pete Becker from friends? Yo I freaked when I heard Peter Beck! He's real!!!
God bless Rocket Lab's ventures.
First time I've seen this rocket. I will follow more closely from now on. Fantastic work. And yes it's the way forward.
Great information on the Rutherford engine.
Nice video, definitely a new subscriber!
Looks promising! Very interesting!
This is just incredible stuff to learn about! 😆🤩Honestly, Rocket lab is the god of small rocket launches and small satellite galore👍🏽
Fun Fact: Mr Rutherford is on the New Zealand (Kiwi) $100 bill.
That’s Lord Rutherford, to us commoners.
Even more fun fact, Lord Earnest Rutherford is on the NZ $100 bill because he was the first person in the world to split the atom, in like 1890 i think it was.. absoliute legend, it's now super awesome to see his name launched into space by a New Zeland company..
Hello and thanks for the information
Thank you for your feedback.
That’sfrikin awesome
Excellent idea.
New Zealand is the new Frontier Mate
Thanks for the information 👍
Pls make more videos on semi-cryo engine and even nuclear propulsion
Thank you for your feedback.
Will do in future.
This engine is super cool
Watch this company some big things happening soon.
super man keep it up
amazing
amazing....sooo cooool!
Ok you are awesome dude
“Will it be able to launch larger sats and astronauts into space” well rocketlab already said “we don’t fly meat” so thats astronauts out the picture and if i recall correctly, they also said small sats was their only target market which with their kickstage orbiter puts them as 100% market leaders for small sats. Maybe they will go with bigger sats but generally satellites are only getting smaller. Is the Rutherford capable tho, with enough of em you could launch anything theoretically.
The also said not doing reusable. Now he is looking for hat condiments after the "I will eat my hat" comment on not doing reusable. So I guess where you start and what you say are subject to change.
@@barbiegirlfriend5752 also very good point to consider! Everything is subject to change. Especially in aerospace
@@barbiegirlfriend5752 wait no reusable, umm i like the engine but not the system
They are going for broke. Neutron is going to be rated for human spaceflight, and will have a payload capacity larger than the falcon 9.
Fantastic tech! This is so amazing, the company looks great. Yesterday I also found out it quoted on the stock market, if you believe in it it could be a legendary run!
I think battery tech will keep getting better, exponentially, for a while longer, with so many companies pushing for a "holy grail" solution. This type of engine might be the future for rockets?
That will be cool
Thank you very much for your nice and fàntastic video .
There should be more advancements in this new technology .
thank you ❤
@@scientia_plus You are welcome .
Stay connected and stay blessed !
Genius...WOW
At 2:22 you say that an inverter changes the battery’s DC to AC for the motors, yet at 2:48 you say that the Rutherford uses dual DC brushless electric motors. So which is it - AC or DC motors?
A brushless DC motor replaces the traditional commutator with solid-state electronics that control power to the motor’s phases, so in a sense it is a hybrid of DC and AC. There is a good Wikipedia article about this.
@@williamhanna4823 Smaller versions of these sorts of motors, electronic speed controllers and batteries have been used for years in model aircraft. Now full size aircraft, such as those produced by Pipistrel, use this sort of technology, but the range is still a tenth to a fifth of that attainable using conventional fossil fuels. Furthermore, the weight does not decrease during flight, as no propellant is expelled, which is why Rocket Lab have ingeniously resorted to dumping a used up battery pack during ascent of the second stage. I'm curious as to whether the first stage battery packs and ESC's will be re-usable after the first stages are recovered.
The power to the motor is variable-frequency three-phase AC. But the electronics that produce the AC are small and located close to the motor. The module is DC powered.
Why use batteries at all. just use a combustion engine and dynamo.
Ese Callum You need a lot of power to drive the pumps. Making a high powered combustion turbine is not trivial. Piston engine is not powerful enough.
New Idea is great ...not to much tubing around the engine not like the Raptors engine..
Well those 2 engines have 2 different objectives
Raptor is meant to be powerfull and reusable
Rutherford is meant to be expendable and quick/cheap to produce
Also rutherford is like 10 times smaller than the raptor so it can be much less complex
Raptor needs tubing or it would overheat. It runs on full flow, which is very hard to handle and raptor is actually the first flown full flow engine
@Aditya Suri Can you explain a little bit more please ?
🤔 Thinking the same, later in the video I realized the size... a compact car vs Truck?
Do those rs connectors have a cover of some kind?
Maybe not something you would do in first stage. As others commented, the energy needed is not weight efficient in large scale. But i think it is an interesting concept for orbital maneuver. At that stage, the engine is smaller, can deploy solar panels to charge the battery back, the battery may be can share with the ship.
As of now, IDK if they can launch heavy payloads in the future, but they can launch plenty of smaller & cube satellites. They just need to expand their launch webcast to include payload deployment.
Great idea 💡 and rocket 🚀! Could they make them also re-usable?
Wait, what? 8:36 - "Will it be able to launch heavy satellites and astronauts in the future?"
_No! Not one bit._ As you yourself mentioned in _the first line of the video_ - 0:01, this whole company is expressly designed for dedicated small satellite launches. Electron and Rutherford will never be human rated, and they will never launch heavy loads.
Rocket Lab may some day, sure. But that's certainly nowhere in their current business model or engineering plans.
Aged like milk
Batteries are the Achilles heel of electric motors and therefore pumps. From what I can understand bigger rockets would run into the problem of battery density. But as Peter Beck has said time and time again they aren't interested in anything bigger then their current rockets.
If batteries improve then we might very well see human rated launch rockets.
Copenhagen Suborbitals is considering an electric pump for their human rated SPICA rocket now under construction, but they have a heat-powered alternative option if the electrical pump isn't good enough.
WoW
Inverter (2:21) for DC motors (2:47)?
I would like to see one day, an engine type

With a lithium-graphite hybrid battery
and some Supercondensers as part of the rocket's own structure.
wish i knew what you were talking about.
That's the special sauce as Elon said... Rapper ll has no pre burners, yo!
There is no such thing as a rocket scientist - It should be rocket engineer!! Thank you
So if battery technology keeps progressing at the current rate. Eventually does it get to a point where these engines are more efficient than a traditional turbo pump fed rocket engine?
Need some help, here. At 2:23 the commentary says the propellant pumps need AC power, yet at 2:45 and 3:58 they are "DC" motors.
Nice video. However, you mention at 2:21 that the electric pump fed rock motor the battery DC current goes through an inverter where it is converted to AC to power the motor. On 2:47 you mention that the motors are brushless DC electric motors. It should be noted that DC motors as their name implies use DC current and hence don't require inverters to provide DC to power the motors. They may use inverters for AC conversion to transform to a higher voltage and then rectified back to DC for motor usage.
this is 100% wrong. Brushless DC motors still need a controller that supplies a pulsed current to the motor. Otherwise, it wouldn't spin.
@@Stefan-rg1ub Right you are. I forgot my "Brushless" DC motor theory. In a regular DC motor a commutator, commutates the electrical supply, which is effectively changing the DC to AC allowing it to rotate. A Brush-Less DC Motor uses an external electronic commutation, in other words, an Inverter. I apologize for my momentary ignorance.
@@WWeronko but if current comes to motor pulsed and commutated is no more DC corrent?!?
@@edmilsonbtu It is still called a brush-less DC motor. Some would say it is not DC any more.
A brushless DC electric motor is powered by direct current electricity via an inverter or switching power supply which produces electricity in the form of alternating current to drive each phase of the motor via a closed loop controller. The controller provides pulses of current to the motor windings that control the speed and torque of the motor. This control system replaces the commutator used in many conventional electric motors.
en.m.wikipedia.org/wiki/Brushless_DC_electric_motor
I hope the electric pump rocket motor is the way of the future. I'm working on a much smaller version for university students to test and learn the intricacies of liquid propulsion.
You'd think Elon would be all over the electric pump and high density batteries.
@@barbiegirlfriend5752 but Elon knows how to count the power he'd need to store in the batteries for the raptors and how much those would have to weight :)
Whats the accuracy and performance percentage?. Whats the failure rate per launch.could it be configured to use multi fuels or combos of fuel?
What are the sources of each and every piece of information provided about the Electric Pump Fed Rocket Engine??
Are you using Vicor power supplies?
Could they tap off some of the fuel & lox to power a turbo motor with generator instead of a batery?.
Not at that value
Light, low-orbit payloads is definitely a market, but it looks like a niche player by design.
But only player in game space x does not bother with 100 kg payload
They really need to see if they can print and billed in spaces
In 2:15 you show a diagram of the electric feed rocket engine from wikipedia with the pumps mechanically attached with a shaft and one electric motor driving them. I think this is not correct for the Rutherford engine, but I cannot find the information online because everybody seems to be sharing this same information.
I think that the turbopumps in the Rutherford engine are not mechanically connected and there are two electric motors. One electric motor for the oxidizer pump and one electric motor for the fuel pump.
The reason to have independent pumps it is because the liquids are different and need different RPM and power to be pressurized. Also with the pumps being independent you are able to independently adjust the flow of fuel and oxidizer and therefore adjust the mixing ratio for the combustion.
Can anyone tell me if I'm correct?
Kind regards.
You can (but not must) have both pumps on the same power source. Both the raptor, most engines use one turbine to drive two pumps. You can adjust the ratio by simply put different pumps size. The fuel/oxidizer ratio is fixed anyway. But I’m not saying what you said is wrong, I don’t know that bit either.
@@edmondhung6097 Thank you!
Was thinking a car size hybrid blimp with these
Hello. Question: What exactly is a dual brushless dc motor? What makes it "dual"?
Two sets of fields on the same shaft with independent control electronics
Would be cool to see tesla use this and electron to also have landing rockets.
I think electron engine is best way to go the space of cheapest budget.
What's the motor speed on centrifuges?
I think they said 42000 rpm
Electrogravitics is the future of space travel
"World's first battery powered rocket engine" - I don't think Rocket Lab used the world's first battery. It would be far too weak for their motor pumps.
Battery powered not battery
@@observeoutofthebox7806 Yes, that's what I - and they - wrote, wasn't it?
@@Anvilshock you said they didnt use the world's first battery. But actually the sentence isn't worlds-first-battery powered
It's worlds first battery-powered pump.
It uses top notch lithium battery cells. That can hold upto I think 37kwh. Powerful enough to turn the pumps and pressurize the fuel into combustion chamber
@@observeoutofthebox7806 I know it uses batteries and for what it is using it. Good job missing the point. Yet ironically, you had to explain _your_ point with the very device whose omission I was mocking with my original comment. Isn't that telling? And in case it's still not clear: Yes, you had to use hyphens to switch the meaning of the sentence from one it has without to the one it has with.
@@Anvilshock mate if its sarcasm you could have just said so.
Tesla literally builds the motors and batteries. I’m sure they can come up with their own version.
Nice video, but I don't like the text to speech
How about plasma jet engine but require efficient source of energy .
Make the rocket reusable. I see that this Electron Rocket Engine is only the beginning of a new direction of aerospace technology. WOW!
It is reusable
2nd Dec for Neutrons Archimedes engine announcement.
So the batteries, a key element in the electric cars and main object of development from Tesla, drives the simplicity and reliability of the Rutherford engine. Who else thinks that Elon Musk and Peter Beck should become best buddies?
May physics and luck be always in their favor.
Limited use for its size and hence limited payloads. Great for small payloads.
cool tech.... but they need to jettison the battery after they are depleted . that's not great for reusability
It might work for small pay loads.

If the motors are DC for what need inverters?!?!
Tesla is very mad now lol
A brushless DC electric motor is powered by direct current electricity via an inverter or switching power supply which produces electricity in the form of alternating current to drive each phase of the motor via a closed loop controller. The controller provides pulses of current to the motor windings that control the speed and torque of the motor. This control system replaces the commutator used in many conventional electric motors.
en.m.wikipedia.org/wiki/Brushless_DC_electric_motor
@@scientia_plus 1 phase to 3 phase is thet correct .
@@scientia_plus so DC power supply, but AC winding current?
The motor is actually an AC motor. The inverter delivers AC at a very much higher voltage (and thus lower current) than provided by the battery alone. All current carrying components (including the motor) can thus be made smaller and lighter. There is a weight saving advantage in this scheme.
I believe the unsung hero of rocket engines will be the aerospike model eventually replacing bell models as soon as material science solves certain current problems it suffers with . Material advancements will make this engine the one enabling single stage to orbit craft commonplace in the very near future. A company in Europe says it already has solve the aerospace engine development problems..I don't have that companies name.. Sorry.

Migjt be confimred to smaller payloads for now. Great job on the design though. Limitation is battery energy density.
Add Dimond batteries, they have been known for 10years now
NZ with a space program. who would of thought. looks like that tech is one step from ICBM stuff.
Now it's time for fuel-powered water pumps
Man what I couldn't do what those electric motors high powered batteries power converters and electronic controls.
They are Tesla manufactured motors. Not Tesla Model S plaid but Tesla made
First you show a diagram of the engine with an inverter that inverts dc power from battery to ac power to power the motor but the you say that the engine uses brushless dc motor.
Using electric motors instead of the turbo pumps is just a matter of fit for the job. They want the highest reliability at these crazy temperatures. Good to see the design competition taking place. the new Raptor has guarded secrets, and Elon talks about reducing battery weight. Elon likes a simple reliable design.
he likes designs so reliable that 80% of the raptors that have flown have failed, hahaha elon fanboy
It sounds really good at 1.25x speed
I use 1.5x speed
Why not just use DC pump? Are there disadvantages?
This was so misleading to me. I thought this was an all electric thrust engine. However still fantastic and the ease of manufacturing is astonishing.
What’s electric thrust? You mean an ion engine? All engines need reaction mass.
@@aldunlop4622 No, he meant warp drive.
When you compare a Nasa engine to rocket lab's sheez looks neat
Nice 35kg 3:43 less crap less can go wrong 👍

Raptor and Merlin engines is Edison(DC- expensive transportation)
Rutherford engine is Tesla(AC - cheap transportation)
Oh. Oh, you guys. You guys, I'm headed offworld the moment i get my printer.
liquid oxygen hydrogen rocket has only 8MJ/kg of specific energy, metal-air battery has up to 40MJ/kg specific energy, if used for full-electric rocket engine, for example heat engine, air scoop resistive engine
instead of sweep single head print, you could make fast lithographic mask printing
electron (vs ion) electric engine should be nice
instead of random powder stacks, you could have quick layer mask powder sheets, then x-rayed to bond
Definitely DMLS/LPBF & not EBM.
i want to make these by the hundred of thousand for 2a purposes
i just nee dmore details and funding, i can produce myself
I think I know why starships keep exploding now. Thanks.
They can print, but they have micro cracks.
Electric motors are not more efficient than gas turbines especially large scale overall. The added weight actually overall reduces capabilities but they do take away less energy from the combustion but this need to be stored in some form which the heavy batteries are for. This would only work small scale. Larger scale such as the raptor engine would require massive batteries and ridiculous size electric motors. If you would increase capacity and power density while decreasing the weight of batteries it would be more applicable for further use in small rockets. But never larger ones without major development in electric motors and battery technology.
Its good for spare flight in space due electric motor not get impact on micro gravity☺️🐼🐼 its will impact bottom side motor from what i see... Need new designer put that motor like normally not like this... Its give impact on bottom side... And the front motor put turbin fan so after spinning not cost more energy from the battery and for cooling ... And if can add auto charging and solar system after on the space... Its can be used space transport☺️☺️☺️...
Nonsense. The motor in the front (second) stage isn't used until the rear (first) stage has thrown it into space with 5 spring loaded pins. This is completely traditional on all multi stage rockets.
@Integza watch this
Heavy payload , need more time .
Screw that. Humans only weigh a few hounded pounds. So this can be a strictly commercial thing which could go a long way because I would definitely ride one.
The battery can also be recharged in situ and/or augmented by thermoelectric devices feeding off the hot combustion chamber.
You say that the motors are DC but in your schematic you have a DC - AC converter?????
